Salt solutions on Mars can stabilize liquid water at low temperatures by lowering the freezing
point of water. The maximum equilibrium freezing-point depression possible, known as the …

Brine formed through the cryogenic concentration of seawater remains one of the least
understood components of Earth's cryosphere. Cryogenic brine is a prominent feature of the …

Several icy moons and dwarf planets appear to have hosted subsurface liquid water. Liquid
water intruding upwards into the icy outer shells of these worlds freezes, forming ice and …

We determine the environmental setting and timing of enigmatic large‐scale chloride
deposits on Mars, examining all available high‐resolution imagery globally, building digital …

Incredible as it is, researchers have now the awareness that even the most extreme
environment includes special habitats that host several forms of life. Cold environments …

Abstract The Wet Chemistry Laboratory (WCL) on the Phoenix Mars Scout Lander analyzed
soils for soluble ions and found Ca 2+, Mg 2+, Na+, K+, Cl−, SO 4 2−, and ClO 4−. The salts …

Antarctic water tracks and ephemeral wetlands are a primary location for biogeochemical
soil processes driving cold desert soil formation. Though the spatial extent of water tracks …

Ice cores and offshore sedimentary records demonstrate enhanced ice loss along Antarctic
coastal margins during millennial-scale warm intervals within the last glacial termination …

ABSTRACT The McMurdo Dry Valleys are a polar desert in coastal Antarctica, where
glaciers, permafrost, ice-covered lakes, and ephemeral summer streams coexist. Liquid …

This study investigates the origin and age of ground ice in the uppermost 1 m of permafrost
in University Valley, one of the upper valleys in the McMurdo Dry Valleys of Antarctica. In …
